Abstract

The invention relates to a hydraulic pressure supply control device used for hydraulic fracturing experiments, and an experiment method thereof. The hydraulic pressure supply control device comprises a diaphragm pump, a booster pump, and a water diversion steel cushion; the inlet end of the diaphragm pump is communicated with a water source pipeline; the outlet end of the diaphragm pump is communicated with a outlet end pipeline of the booster pump, and another outlet of the outlet end of the booster pump is communicated with a water diversion channel pipeline of the water diversion steel cushion via a high pressure pipeline; the water diversion steel cushion is detachably arranged on the surface of a test piece in a press machine; the booster pump is used for delivering high pressure liquid obtained via pressure increasing into the test piece via a water diversion channel. Operation of the hydraulic pressure supply control device is simple; continuous, stable, and accurate providing and recording of water pressure can be realized in a large pressure range. In hydraulic fracturing experiments, the hydraulic pressure supply control device can be connected with a single-shaft, a double-shaft, or a three-shaft press machine for test piece hydraulic fracturing; equipment connection and operation are simple; water pressure supply is stable; pressure value can be automatically controlled; detailed recording of pressure value and pressure change is realized; and experiment effect is excellent.

Description

technical field [0001] The invention relates to a water pressure supply control device and a test method for hydraulic fracturing experiments. Background technique [0002] Hydraulic fracturing is an emerging technology developed in recent decades. Its essence is to use the characteristics of fluid pressure transmission to inject fluid into porous media, so as to promote the formation of fractures and expand in a certain direction. Since hydraulic fracturing was adopted in the petroleum industry, it has played an important role in the exploration and development of oil and gas fields. Since the first hydraulic fracturing in the United States in 1947, great progress has been made both at home and abroad from theoretical research to field practice. The hydraulic fracturing laboratory simulation test is an important means to intuitively understand the crack initiation and extension, and to explore the crack initiation and propagation mechanism. It is of great significance to b...
